[jira] [Created] (ODE-968) Ode Extension XPath functions executes
twice.
Jayant Vaish created ODE-968:
--------------------------------
Summary: Ode Extension XPath functions executes twice.
Key: ODE-968
URL: https://issues.apache.org/jira/browse/ODE-968
Project: ODE
Issue Type: Bug
Components: BPEL Runtime
Reporter: Jayant Vaish
Priority: Critical
When the XPath query call the ode extension xpathFunction for the first time it expects return type of NODESET, If in case it returns something else then the exception is thrown and in the catch block it executes that function again.
To reproduce this issue, unzip the attached project in your server's var/deploy/
Set logging level debug for "org.apache.ode.bpel.elang.xpath20.runtime.JaxpFunctionResolver.DomToString"
Now, while running this process "org.apache.ode.bpel.elang.xpath20.runtime.JaxpFunctionResolver.DomToString.evaluate(List args) throws XPathFunctionException" will be executed twice.

Jayant Vaish commented on ODE-968:
----------------------------------
The problem with solving this issue is we are not able to get the return type of XPathFunction in advance.
As the expression containing the function information is by net.sf.saxon.xpath.XPathFunctionCall. And there is
no way we can get the return type from this. Also net.sf.saxon.xpath.XPathFunctionCall contains the function information
but it is private.

This issue is similar to ODE-969

Set logging level debug for "org.apache.ode.bpel.elang.xpath20.runtime.JaxpFunctionResolver.DomToString"
Now, while running this process "org.apache.ode.bpel.elang.xpath20.runtime.JaxpFunctionResolver.DomToString.evaluate(List args) throws XPathFunctionException" will be executed twice.

Jayant Vaish commented on ODE-968:
----------------------------------
In org.apache.ode.bpel.elang.xpath20.runtime.XPath20ExpressionRuntime.evaluate(OExpression cexp, EvaluationContext ctx) throws FaultException, EvaluationException{
.....
try { someRes = evaluate(cexp, ctx, XPathConstants.NODESET); } catch (Exception e) { someRes = evaluate(cexp, ctx, XPathConstants.STRING); }
....
}
evaluate(cexp, ctx, XPathConstants.NODESET); is responsible to call the ode extension xpath function, but that function return type is not NodeList (For example it's return type is String).
So, it throws exception as String value is not converted in NodeList.
Then in the catch block it again execute that function.
